May
As June hits and summer temperatures ramp up, your garden’s water needs change dramatically. The goal this month is maximizing efficiency — getting water deep into root zones before the sun can steal it away.
1. Water deeply and infrequently
Avoid the temptation to give your garden a light, daily sprinkle. Shallow watering keeps roots near the surface, making plants highly vulnerable to heat stress. Instead, aim to water deeply only 2 to 3 times a week.
The goal: Provide about 1 to 2 inches of water per week, depending on how hot it gets. Soak the area, then check depth with a trowel — you want moisture penetrating 6 to 8 inches down to encourage roots to grow where the soil stays cooler.
Smart irrigation controllers can automate deep watering schedules and adjust runtimes based on local weather conditions, helping maintain healthy root growth while reducing unnecessary water use.
2. Time it for the sweet spot: 5 AM – 9 AM
Timing is everything in June. Watering in midday sun is incredibly inefficient — a significant percentage of water evaporates before ever reaching the roots.
Watering early gives soil maximum time to absorb moisture and allows foliage to dry during the day, helping reduce the risk of fungal diseases. Leaving plants wet overnight, by contrast, can encourage pests, mold, and disease.
Smart timers — whether for in-ground systems or hose-end faucets — can handle early-morning scheduling automatically, even when you’re asleep or away from home.
3. Use cycle and soak to prevent runoff
If you have clay soil or sloped areas, water will often pool and run off before it can sink into the ground. The fix: split watering into shorter segments.
Instead of running a sprinkler zone for 12 continuous minutes, set your timer to run three 4-minute cycles with 30 to 60 minutes between each session. This gives the ground time to absorb water like a sponge, preventing waste and pooling.
Many smart irrigation controllers include cycle-and-soak capabilities that automatically break watering into multiple shorter runtimes.
4. Do a mid-season inspection
Irrigation systems endure a lot of wear and tear by June. Turn your system on manually and walk the zones to look for hidden water-wasters:
- Clogged, buried, or broken sprinkler heads
- Sprinklers spraying hardscape instead of landscape
- Drip line breaks, leaks, or popped emitters
- Loose fittings or leaking connections
For repairs, push-to-connect fittings can simplify maintenance and create reliable connections that keep your system running efficiently through the summer.
5. Transition to drip and protect with mulch
If you’re still using overhead watering for garden beds, shrubs, or trees, June is the perfect time to switch to drip irrigation or soaker hoses. Delivering water directly at the base of the plant minimizes evaporation and ensures it reaches the root zone where it’s needed most.
Bonus tip: Once your irrigation is dialed in, lock that moisture in place with a 2- to 3-inch layer of organic mulch — shredded bark or compost both work well. Mulch acts as a barrier against the summer sun, keeping soil cool and significantly reducing how often you need to water.
June Is the Month That Sets the Tone for Summer
Summer watering doesn’t have to mean higher water bills or wasted water. By watering deeply, scheduling during the coolest part of the day, preventing runoff, maintaining your system, and using drip irrigation where appropriate, you can keep your landscape healthy while using water more efficiently all season long.
